DWQA QuestionsCategory: ProgramWhat's better about this kind of JSON string
PHP rookie asked 2 months ago
showdesc({"date":1505647332472,"content":"<div style=\"text-align: center;\"></div>"})

Like this kind of head and tail are included, how to extract the contents?
I used STR first_ Replace showdesc (and}) is not suitable

This is the data in jsonp format, that is, a JS code fragment. You can create a function with the same name and accept it

    function showdesc(data) {
    showdesc({"date":1505647332472,"content":"<div style=\"text-align: center;\"></div>"});
    //var str = 'showdesc({"date":1505647332472,"content":"<div style=\"text-align: center;\"></div>"})';

You need to see more regular

No son answered 2 months ago

If it is a fixed format, you can directly intercept the string.
Someone has already said the regular matching scheme.

If it is fixed, then as said above, regular can be used
If it’s not fixed, you can find the first one from left to right
Then do a Java interception:

str.substring(str.indexOf("("), str.length - 1);

This string is called jsonp:
So find the intercept location
